American Sign Language: "I am..."

The other day I got a "Signmail" message from a video relay
interpreter.
She used the "I am..." sign -- as in "I am interpreter number
675..."
Of course the "I am..." sign has been around for longer than I've
been alive -- but I've never seen it documented anywhere. So, here
you go.
You point to your upper chest area with a slightly bent hand (or
even a flat hand, but at this angle the slight bend works best) and
then smoothly move your hand down the length of your torso. You
don't touch yourself with this sign -- rather you just use a
sweeping gesture. If you are up on stage or in a theatrical or
boisterous mood then do the sign larger (further down the body)
and/or use a flourish at the end.

"I am ..."

Usage Notes:
I wouldn't do this "I am" sign if I were meeting someone one-on-one
or in an in-person small-group setting. The relay interpreter
who used it did so in a setting where she was just matter-of-factly
stating that she was "to be known as" "interpreter 675."
If you meet someone and want to tell them who you are you should
just point to yourself with an index finger and then spell your name
(and add your name sign if you have one).

The "I am" sign is good for such meanings as:
* "You may call me Franscisco"
* "I am known as..."
* "I'd like to present myself, I am..."
* "Moi"
* "By way of introduction I am..."
* "Ladies and Gentlemen, I am..."
